Turn that screw underneath, it should improve the situation.

(the larger one in the center, not the small one)


Been working it and oiling it, however, I still need to tap the underneath of the table to unstick the table after I tighten and loosen the table.

I think the one on the right is for picking the stake out of the box. That other one looks home made it doesn't match the others. About locking, have you unscrewed it all and cleaned it all out?


Yes I have cleaned it. I adjusted the big screw on the bottom after oiling the hole and I can loosed the table by tapping the edge with a screwdriver. Then I align the hole and and turn the knob at the back to rotate the internal cam, and it does lock. The problem is that when I loosen the knob and thus the cam, the table only loosens slightly and I need to knock it again with a screwdriver to free it up. Would love a cutaway of the stacking tool. Any suggestions. May be internal corrosion.

the table should come right off when the screw is removed, and the knob pulled out. Maybe you have corrosion or gunk under there...


I can't actually pull the screw out after removing the bottom 2 screws. It seems to jam. But what you are saying is that once I pull the rod out the back. The table should lift straight off, correct?

Jdrichard,

The table locking mechanism is a crankshaft type of cam similar to the mechanism used to lock in the head and tail stocks of watchmaker lathes. These mechanisms can become worn with use and may require some machining techniques to bring them back to working order. To isolate the problem place a small shim (tin foil) between the locking cam and the hole in the shaft that pulls the plate down. If it now locks then that is the problem. To fix you will have to build back the cam or the hole.

Update on seized staking set. Took out the locking screw and loosened the cam shaft and then knocked out the shaft with a small hammer (scratched the nickel plating on the side a bit, but it needed convincing). Then I removed the table by knocking it with a punch from the bottom. The complete lot fell out. Then I took 1200 grit sandpaper and sanded the hole where the locking cam fits . Did a bit of this as there always some corrosion. Lastly I cleaned the table in lighter fluid and then alcohol and then I re-oiled once dry. Reassembled it and it works like a charm. Loose until I turn the back dial and then tight. Then turn the dial again and the table is once again loose.

Thanks guys for the help and suggestions. I am operational and will be knocking on the balance and roller table once I get the right jewel for a 21 J Illinois PW I have been working on. I am in deep now and have a jeweling set coming in the mail next week. Seitz full set.https://vimeo.com/183234528

      I've been intrigued by everyone's input here...so I decided to give this a shot. I bought the"typical" Pearl watch-machine basket and trays, for about $65. The trays are good,..the housing is a nightmare ! Thought it would take the mixer off my bench at anything above about 200rpm. The housing is cast of course,..and it's not "true" at all...so the harmonic vibration was insane. So,..I bit the bullet and bought the Elma housing and top. Not the baskets though, as the Pearl one's fit the Elma. Saved a bunch there. The basket and lid came to about $80 with shipping. The opening in the Elma top is 8mm, and the shaft that came with my stirrer is 6mm. I bought a piece of steel tube, 8mm O.D., and 6mm I.D. Cut off about an inch of the tube, and drove the rod into it. Gives a really snug fit.... Lightly champfered the leading edge of the 8mm section, then lightly tapped it into the top of the Elma lid. Spins like a dream now So... I have about $240 total into this including jars and steel mesh for the wave breakers   I'm pretty happy Best to you all   Randy
